I came up in some of the eairly days of the repeaters on ham radio. Around 1972 or so. I have put together 2 of the VHF einginnering 2 meter repeaters and one 220 version. Used several 220 Clegg repeaters and still have a Clegg 220 rig running . Used it for RTTY. Good little rig for the age and price. it would stay keyed down for over 30 minuits while sending pix tapes. I have not used the Hamtronics boards. One group I was involved with had an old military repeater . They bought a Spectrum and three of us spent over an hour on the phone with them trying to get a transmitter working on a voltage low enough a 12 volt battery could be used for back up . Never did. We were in the telephone comapny shop where one worked and the other was employed in the airlines in their radio ( or whatever the FAA has) shop. We never did get the Spectrum working on the battery . Anything below about 13 volts and it would flake out on us. Actually spent about 3 nights one week with the Spectrum people. It never did work as well as the old military repeater that used tubes and hard telling how old it was.
>From all the above is how I rate the Spectrum. It is sitll good for a door stop at best. ----- Original Message ----- From: "skipp025" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Tuesday, January 06, 2004 11:41 PM Subject: [Repeater-Builder] re: request for spectrum repair help It's very disappointing to me reading most of the replies to Kevin's request for help repairing his Spectrum Repeater. Most of you would rather fire off wise cracks about Spectrum equipment than help him out. While Spectrum seems to be very corneous rectum about customer service, their products do work for the most part, when properly set up and cared for. It's not rocket science to research and improve even the most basic circuits. Most of you appear to have never seen a VHF Engineering Receiver, early repeater boards from 60's and 70's. This would include the famous Clegg 220 repeater made from a split radio. Early repeater layouts are where many of us "cut our teeth" and learned how to make these less than perfect circuits perform as best possible. I've got quite a bit of Spectrum equipment; their more recent receivers are pretty nice. Their transmitters are a mixed bag, but every one I have seems to work as expected for what each circuit is.
